To all whom it may concern:

Be it known that I, ERNST VALDEMAR GAN DIL, a citizen of the Kingdom ofDenmark, and aresident of Copenhagen, Denmark, have invented certain new and useful Improvements in Milking-Machines, of which the following is a specification.

This invention relates to a milkingmachine with a separate appliance for each teat, with pads of such a shape that they keep said teat securely fixed in the correct posi tion without admitting of any sliding or rolling motion. The movement of these pads is also perfectly natural and in strict conformity with the acknowledged principles for the process of milking, besides which the pads work on the glands above the roots of the teatsa condition which is absolutely necessary for milking the cow perfectly dry.

The construction of my improved machine is very simple, which consequently also renders the operation of same easy and effective. It may also be pointed out that lubrication of the machine is quite unnecessary, which is a great advanta eas by this means contamination of themIlk by impurities is obviated, while as said milk is gathered in a reservoir fitting closely to the bottom part of the machineany impurities from outside are prevented from entering.

In order that my said invention may be readily understood and carried into effect, I will now proceed to describe the same fully, with reference to the accompanying drawings, in which Figure 1 is a plan view of one form of machine, the cover being removed. Fig. 2-is a section on the line I I, Fig. 1. Fig. 3 is a section on the line II II, Fig. 1, and Fig. 4 illustrates a modified form of apparatus.

In the frame 2 of the machine is mounted a spindle provided with a handle k, which by means of a gear-wheel and a crank moves the rod Z backward and forward. This rod is in connection by means of a pivot-bolt n with a bed-plate m, to which is also consequently imparted a reciprocatory movement. In the bed-plate m are mounted two screws 25, of which one carries two blocks n, for the movement of which there are rectangular slots 1 in the bed-plate m. The screws t are provided with right and left handed threads, so that the blocks n may be caused to travel toward or away from each other by operating said screw. The blocks n each form at its upper end a cylinder having a bottom 0 secured to it in some suitable manner. Inside of this cylinder a case i slides, in which is placed a spiral spring which tends to force the case i outward. The case i is connected by the bolt h with the plate (1 and is pressed against this latter by the aid of the pin a. The plates (1 have on their sides pins p, which slide in slots 9 in the frames The blocks n are also supplied with a pin 1" below the case i.

Now when the rod Z, Figs. 1 and 2, reciprocates the bed-plate m and the blocks n the case i and the plates (1 to the left of the pins 1) will slide in the slots g until they reach the ends thereof. By this the movement is stopped on top, as the case i by the further movement of the rod Z slides into the cylinder at the upper part of the block n through the compression of the aforesaid spiral spring. The movement below is, however, continued by the pin 7' coming into contact with the plate d, which is thereby forced farther forward in such a manner that it takes up a slanting position.

The aforesaid frames j; in which the plates (1 move backward and forward and of which there are four, one for each teat, carry just opposite said plates d other plates 0, which by means of screws and nuts g may be adjusted so that the distance between the plates e and d will correspond to the thickness of the teats. The plates 0 and d are preferably supplied with pads c, of soft india-rubber, on

that side next the teat. These pads are respectively concave and convex on the outside, so that the teats are held firmly, but still softly and with sufficient grip to prevent them from sliding.

The frames f may be moved two by two by screws 8 with right and left hand screwthreads, so that said frames may be brought closer to or farther from each other in pairs, according to the distance between the teats. The screws 8 have bearings o in the frame 2 and pass through the lower parts of the framesf, to which are screwed half-nuts y.

In the frame of the machine 2 and under each frame f a hole w is provided, through which the milk runs into the receptacle A, which is placed under and is fitted tightly to the frame 2. In said frame, as also in the cover a, are holes through which the teats are inserted in the machine. At the upper part of the machine loops 3 are provided adapted to receive swivel-hooks to which are fastened straps that serve for keeping the machine suspended while the milking operation is proceeding.

The machine is used in the following manner: By turning the nuts 9 the plates 0 are so adjusted that the distance between the pads corresponds to the thickness of the teats at the root. The frames f are adjusted by the screws 8 so that the distance between them will be the same as the distance between the foremost and hindmost teats, respectively, the cases i with the plates (1 being at the same time adjusted by the aid of the screws 25. The straps are then hooked into the loops 3 and the machine is attached to the animal in such a manner that the cover, which is supplied on top with a non-conductor of heat, touches the udder while the teats are simultaneously'inserted in the four holes of the cover. If the handle 7c is now turned, the bed-plate mwill be reciprocated, and the cases i will push the plates d, which turn around the pins p, until these latter reach the bottom of the slots g, by which means the teats are pressed together at their roots. By continued motion the cases i will compress the spiral springs, while the pins 1" carry the lower part of the plates d farther on, and thus force out the milk which is in the teats. By continued turning of the handle 7:: the plates at are carried back from the frames to the left, while the plates (1 to the right now move forward, thus milking the teats at that side. Thus the teats are milked in rotation two by two.

Fig. 4 shows a modified form of apparatus in which the bed-p1ate m (which in the machine described above is common for all four blocks and frames and lies between them) is divided into two bed-plates m and m arranged outside the frames f. Thus on each of the beds are two frames. To the rod Z is fixed a piece 5, forming a bearing for a screw 6, having at one end a right-handed thread and at the other end a left-handed thread, for which screws the beds m and m form the nuts. By turning the screw 6 the beds may be caused to approach to or move away from each other, so that the distance between the lines 7 and 8, Fig. 4, can be made to equal the distance between the foremost and hindmost pair of teats, so that the mechanism proper for effecting the milking may be made to fit still closer than by the means described with respect to the first-mom tioned apparatus. The other parts are essentially the same as specified above.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a milking-machine, the combination of a pair of squeezers supported to cooperate,

a block having a yieldable connection with one of the squeezers at its upper part, and also a swinging engagement with the squeezers at its lower part, the block being movable to carry the squeezer to and from the other squeezer, and means for reciprocating the block.

2. In a milking-machine, the combination of a pair of squeezers, a member pivoted to one of the squeezers at its upper part, a block having a yieldable connection with said member, and having a swinging engagement with said latter squeezer at its lower part, the block being movably supported to carry said squeezer to and from the other squeezer, and means for reciprocating the block.

3. In a milking-machine, the combination of a pair of squeezers, a member pivoted to one of the s ueezers at its upper part, a block having a yieldable connection with said member, a pin on the block arranged to impinge on said latter squeezer at its lower part, the block being movably supported to carry said squeezer to and from the other squeezer, and means for reciprocating the block.

4.. In a milking-machine, the combination of a pair of squeezers, a member pivoted to one of the squeezers at its upper part, a block having a yieldable connection with said member, a pin on the block arranged to impinge on said latter squeezer at its lower part, the block being movably supported to carry said squeezer to and from the other squeezer, a stop for limiting the movement of the yieldably-supported member, and means for reciprocating the block.

5. In a milking-machine, the combination of a pair of squeezers supported to cooperate, a block having a yieldable swinging connection with one of the squeezers at its upper part and also a swinging engagement with the squeezer at its lower part, the block being movable to carry said squeezer to and from the other squeezer.

6. In a milking-machine, the combination of a set of four milking devices, a single member arranged to operate all of the devices, and means for adjusting the positions of each of said devices relatively to the others.

7. In a milking-machine, the combination of a set of four milking devices, a single member arranged to operate all of the devices, and means for adjusting the relative positions of each said device in two transverse directions.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
